Hi Solo,
I'm allergic to grass and several other plants, yet one of my favorite hobbies is gardening. Go figure. I got a lot of eye infections and allergy symptoms from it. A friend told me about some homeopathic eye drops from the maker 'Similasan', available in drug stores and natural food stores.
I thought 'oh sure, sure' but I tried it and I'm telling you honestly, those eye drops worked better for curing eye infections and eye allergy symptoms than any prescription. I use the allergy eye drops and the pink eye drops when I have an infection. They work like a champ.
With all this said...this is your beloved daughter, and while you can try these drops and see if they work for allergy symptoms you must take her to a physician if her eyes don't improve within a day's time.
Also, if it is an infection and not just allergy stuff, changing linens and hand towels daily is a must, so that she'll get well and the rest of the family won't pick up conjunctivitis.
